How To Replace A Blown Fuse
Replace A Blown Fuse. Discover what a fuse does, which fuse to use and how to read a fuse diagram. This video will help you in your hour of need!
Step 1: You will need
- 1 set of fuses
- 1 fuse puller
- 1 pair of tweezers
Step 2: Secure the car
Secure the car.
Switch off the ignition. No electricity should flow during a fuse check.
Apply the parking brake....
In a manual car shift into 1st gear, in an automatic vehicle put the gear stick into the parking position.
Step 3: Locate the fuse panel
Fuse panels are usually located under a cover below the steering wheel, left of the column.
Remove the cover. It has a fuse diagram printed on it. You will see the fuses sitting in the panel.
You will immediately notice the different colours indicating different ratings.
If you have trouble finding the fuse box consult your car manual for details of the location.
Often the fuse panel is found under the bonnet. Remove the cover and access the fuse panel.
Step 4: Check the fuse diagram
Check the fuse diagram.
The fuse diagram is a simplified numerical chart that explains which fuses correspond to which device or system. The devices are represented by easy to understand symbols.
Work out which fuse needs to be removed for inspection.
Step 5: Remove the fuse
Remove the fuse now.
To remove the fuse that you have singled out, simply pull it from the panel. Use the plastic puller for doing this - otherwise, use your fingers or tweezers.
Step 6: Check the fuse
Check the fuse.
Determine if the fuse in question is blown. If the metal link inside the fuse is separated, the fuse has melted. If it looks normal it can be plugged back in, however, you may still have electrical problem. In this case, it's best to consult a mechanic.
Step 7: Replace the fuse
Replace the fuse.
Place a new fuse with exactly the same amperage rating in the puller.
Be sure to use the correct rating, remember to go by the colour and the number stamped on the fuse. SAFETY WARNING !
A fuse with the wrong rating may damage the electric equipment it's designed to protect. Avoid a fire hazard and consult a mechanic if the initial problem remains after you've replaced the fuse.
- Push the new fuse firmly into its slot in the fuse box. If it is askew it will not work.
- Push it down with your fingers for a correct fit. A useful tip.
If you're left without any spare fuses you can still take a fuse from a non essential circuit. Check if your car has a working cigarette lighter and take the lighter out of its socket to remind yourself that you will have to replace the fuse later.
- Check the diagram in order to find the lighter fuse.
- Take out the fuse and put it into the required circuit slot.
Alternative devices to temporarily take a fuse from are the radio or, if temperatures allow for it, the rear window heating.
Step 8: Check circuit
Check the circuit.
Switch on the ignition and switch on the circuit in question.
If you cannot operate the device, and the new fuse blows immediately there is a problem that should be checked by a mechanic.
If the device works correctly after fuse replacement, you can quickly check if the main electrical functions on your car work properly.
